Hello to all

after having my 1st net runing at home I got this strange problem.

I use now my laptop often with free AP in the city. Today (after playing a bit at home with crossed cables)
I experience a very strange problem on the road. Excelent signal with a spot I usually have good connection.
My Alfa USB says good signal and good link. (4/5 bars). I do have connection but it is crawing low: 30kbit/sec...
(2.4KBPS!!!!!). The same laptop at home has good wifi connection speed.

I noticed for the first time ( is it normal?) that I have an " internet gateway " connection ON only when I am
connected on the road with an open wireless AP ? at Home I have one which is not configurable as it is not
and open AP (WEP). On the road I see a configurable gateway connection.

I also installed latest emule a few day ago, and oppened 2 ports TCP/UDP recently.... could that be the reason?


both laptop and destop are XP pro SP2. I haven't been able to have fine filesharing permissions yet....
on a work group (with same user name and password) ... it's not a big issue, I just think maybe it's connected somehow.

At home the laptop as well as my desktop keeps looking for my bluetooth to connect to internet.... intermitantly even though the desktop XP is already on the net wia the wifi ...

Is it buggy the XP networking ...? vista makes an improvement in that respect?

best.

here is ipconfig

a few issues can cause your problem.

#1) Multiple devices connected to the same access point can cause network slowness, remember your Wireless network connections, are shared bandwidth, also if one person is connected at a slower speed, then this also causes everyone else to become slower, as there is a delay waiting for this to finish sending data.

#2) Multiple Access Points in the neighbourhood on the same or close to the same channels. This has the same reason as above, except you must also wait for others to finish sending on other access points as well. The frequency is a shared media. Ideally you should only use channels 1, 6 or 11 This will give you the best signals, all other channels can have interference from anything on those channels.

#3) if you are using 802.11b/g 2.4GHz phones can cause problems with your access points, as this is in the same frequency as your 802.11b/g AP. This can also apply to bluetooth as well.

#4) Location of the Access Point, if it's close to metal, this can block the signals. So can water, and thick concrete walls.
